Click the Export tab. You should now see a list of the types of data that will be exported. This includes the channel message history, links to shared files, archived channels, and integration activity logs.
- It’s not possible to export private group history and files, direct messages, edit or deletion logs.
The export file will now be generated. Once the export is complete, you’ll be notified that a file the file is ready to download.
You’ll see this link on the Export screen under “Your team’s exports” once the export is complete. Your computer’s Save dialog box will appear.
The exported data will now download to your computer. Once the download is complete, you can select data to import to the other channel.

Part 2 of 2:

Navigate to https://my.slack.com/services/import . If you’re still on the Export screen, you can simply click the Import tab near the top of the screen.
It’s the blue button under “Current import.” If you’ve exported more than one file, they’ll all be listed on this screen—be sure to select the correct file before clicking this button.

Map users to import. Since you’re not merging workspaces, you shouldn’t need to do anything special to the users. Select Map users when possible, and manually configure the rest from the drop-down menu under the “Users” header.
- To change how the user is merged, click the menu and select a different option. You can create a new account and invite the user, create an inactive account and invite them later, keep the user’s messages, or choose not to import them at all. ^{[1]

Since the goal is to merge channels, click the drop-down menu next to the channel you’re exporting, select Add to an existing channel , then select the other channel.

Click Save Changes . Now you’ll see a preview of what will be imported.
- If you want to make any last-minute changes, click No, I want to change something first.
The selected data will now import back into Slack. Once the import is complete, you’ll receive an email confirmation, and the channels will be merged.
The data from the old channel now appears in line with that of the new channel.
